To have been banned from a message board and have had any and all evidence of your existence on that board removed permanently, usually done without warning, notification, or explanation. Origins: from the bbs handle of a customer of Nebraska football message board (slowhand) who was one the first recipients of such action on that board, soon to be followed my many other customers of that board who began to use the term "slowhanded" to describe the action

Because the site administrator didn't like fans who could actually make a cogent argument, he was slowhanded.
